How to maintenance your mini excavator?

Do you know how to maintenance your mini excavator by yourself?

After view this video you can do by yourself:

Excavator Maintenance in Plateau

The excavator working in Plateau may go wrong because of the extreme environment. Only knowing the reasons can we solve the problem to reduce the machine downtime and make the maximum productivity. With high altitude and low air pressure, the boiling point of the coolant decreases about 10℃ when the altitude increases 1000 meters, the boiling point decreases to 90℃ when the altitude is over 4000 meters. The decline of the coolant boiling point will cause the engine “boiling” and block the fuel pipe, making the engine be short of fuel supply and power declining. The oxygen is rare in the plateau, which is 90% of the plain. And the oxygen declines 10% as the altitude increases per 1000 meters. The declining oxygen results in heavy air mixture which can’t be sufficiently burned and makes engine produce dark smoke and reduce the power.

The roads in the plateau is rugged and steep, so the excavator needs to frequently change the driving power and speed to adapt to satisfy the complicated road conditions, which will lead to clutch separation and increase abrasion. The long and steep slopes increase the tractive resistance and make the clutch bearing overload, which may damage the clutch. And driving in the plateau needs super operating skills, otherwise, accidents may happen. Frequent braking will increase abrasion and cause damage to the machine.

In order to achieve excellent performance, the hydraulic excavator needs to be maintained regularly. The fuel oil should be used as specified. The parts should be checked to make sure the engine power is set as specified. Pay more attentions to brake and rotate system, which bears more loads to keep safe and reliable.

Motor Grader Daily Maintenance

Motor grader is used very often in the road building and leveling. It is troublesome when the machine breaks down during the working process under a tight working schedule. In case of emergency, construction equipment daily maintenance is very important to keep the machine in a good condition all the time. The followings are some guidelines about the road machinery daily maintenance.

Engine is the heart of the construction equipment, the machine will stop working if the “heart” goes wrong, so more attentions should be paid to the engine of the motor grader. Before starting the engine, we should check the fuel level to make sure the machine can operate normally. What is should be noticed is that the fuel should not be filled too full since fire will be caused if the fuel overflows under high temperature. Check the fuel pipe and fuel tank to avoid any leakage. And the remaining water and other sediment should be discharged every day to keep the fuel tank clean and purified. The coolant should be added enough to keep the machine work normally. The radiator should be checked regularly to keep the machine cool and the damaged radiator should be changed immediately to keep the machine operate smoothly.

If only you master the above maintenance guidelines, your motor grader will operate in high efficiency and create more profits for you.
